How it works and assumptions
This calculator estimates total gravel cost from volume, with support for per-m³ or per-tonne pricing modes and an itemized breakdown.
- Enter volume: Total gravel volume in cubic meters (m³).
- Select price mode: Per m³ if your supplier quotes by volume, Per tonne if they quote by weight.
- Enter price per unit: Your supplier's quoted price in the selected mode.
- Set waste factor: 10–15% is typical. The calculator adds this to your base quantity.
- Select material: Used to calculate weight (shown as a secondary result) and to convert between per-m³ and per-tonne pricing.
Per m³ formula: Total Cost = (Volume + Waste Volume) × Price per m³
Per tonne formula: Total Cost = (Volume + Waste Volume) × Density × Price per tonne
